Brushed alternator: In brushed alternator DC voltage for
field excitation (located on rotar) is provided from DC
source through contacts of slip ring and brushes.

Brushless alternators: In brushless alternator DC voltage
for field excitation (located on rotar) is supply through
rotating bridge rectifire (located on rotar) and high
frequency ac supply which is generated in winding which is
also located on rotar.
To provide excitation supply for main alternator field
winding we are not require to use brush hence it is called
brushless alternator.

Permanent magnet alternator: This type of alternators are
usually small capacity alternators, for this permanent
magnet is place on rotar hence we are not require to
provide any field magnetisation supply.
